During meditation, one may study, think and deliberate on the Seven Factors of Enlightenment as well as on their antithesis, the Five Hindrances.[3]

Again according to the Samyutta Nikaya, once when the Buddha was gravely ill he asked Venerable Mahacunda to recite the Seven Factors of Enlightenment to him. In such a way the Buddha was cured of his illness.[4]

In the Visuddhimagga, in a section discussing skills needed for the attainment and maintenance of absorption (jhana), Buddhaghosa identifies the bojjhangas in the following fashion:

"Strong mindfulness ... is needed in all instances...."

"When his mind is slack with over-laxness of energy, etc., then ... he should develop those [three enlightenment factors] beginning with investigation-of-states..." (i.e., dhamma vicaya, viriya, piti).

"When his mind is agitated through over-energeticness, etc., then ... he should develop those [three enlightenment factors] beginning with tranquillity..." (i.e., passaddhi, samadhi, upekkha).[5]

↑For an example of a discourse that includes the juxtaposition of these two sets of phenomena, see the Satipatthana Sutta. For a group of discourses in which these two sets of phenomena are juxtaposed, see SN 46.31 to 46.40 (Bodhi, 2000, pp. 1501, 1589-94).

↑Buddhaghosa & Ñāṇamoli (1999), pp. 129, 131. Note that Buddhaghosa clearly references the last six bojjhangas in the last two cited statements. The first statement about sati (mindfulness), while immediately preceding mention of the bojjhangas, is technically in reference to the five spiritual faculties (indriya).
